'LIFT-PUMP.

SPECIFICATION forming part of 4Letters Patent No. 224,331, dated February 24, 1880.

' Application filed December 2,9, 1879 I Pumps; and I do hereby declare that the followingis a full, clear, and exact description thereof, reference being had to the accompan yin g drawings, and to the letters of reference marked thereon, making a part of this specification. 1

The nature of my invention consists in the construction and arrangement of a pump, as will be hereinafter more fully set forth.

In the annexed drawings, Figure l is a side elevation of my improved pump. Fig. 2 is a `longitudinal section of the same.

A represents the pumpLstoek, provided with spout or outlet B, and having at its lowerend the cheek-valve a. I I

` At a suitable point an air-tight drum, C, lsurrounds the stock A, said drum communi` eating, at its lower end, through apertures b,

` I with the interior of the stock.

ID is the )luno'er )rovided with the valve l b 7 l d, and attached to the rod F, which passes up through thehead E of the pump-stock.

0n the rod F, within the pumpstock,'is `a I I collar, e, to which one end of a spiral spring, I 3o I, is attached, said spiral spring surrounding `,the rod and having its` upper end attached to 1 the head E, as shown.

The upper end of thefrod Fis provided with f I ahandle, G. By pressing down on this han- I time expandingthe spring I. This spring,

die the plunger forced down, at the same then, will throw the plunger up again, or, at xleast, assist in moving the plunger up.

I `The plunger and valves are all working be- I low the air-drum, so 4that when' the water is drawn by theI plunger, instead of lifting all `the weight of the water at once, it will escape through the holes b under the compression of I I the air, which wil-l immediately force the wa- I f p I I ter back through said holes and up the stock,

making aliowing stream.

I `On the plunger is a metallic swaged band,

It This `band is molded on the plunger and then turned down to a feather-edge, so that when the leather c' is sewed on the plunger it may extend" partially upon the band, making again, and this can be repeated time and again until the leather is nearly all worn out.

The plunger-rod F and spring I are so arranged that when the spring is closed the handie Gr will stand'about a foot or fourteen inches above the head, so that, in pumping,

the operator will pump downward, while the spring will make the upward stroke, making the operation of pumping' entirely easy, especially in connection with the air-chamber.

Below the platform ofthe well, at a suitable point, is a vent-hole, x, to allow the escape vof water to prevent freezing. This vent is closed by a valve, m, attached to a spring, H, and operated by a rod or wire, n, from above the platform. i

The spring H is made of a single piece of wire bent and twisted to form the arms s, which are soldered or otherwisefastened to the pumpstock, and then the coils t t, the center ofthe wire forming the double eye and lever e, to which the rod or wire 'n is connected and the valve m attached.

I Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The wire spring H, constructed to form the arms s, eoilst, and lever t, in combination with the stock A, having veut w, the valve m, and rod or wire n, substantially as and for the purposes herein set forth.

2. As an entirety, a lift-puinp consisting of the stock A, having a uniform internal dialneter, air-chamber (J, surrounding a portion of the same, piston D, constructed as described, rod F, and spring I, all substantially as and for the purposesy herein set forth. f

In testimony that I claim the foregoing I have hereunto set my hand this 10th day of December, 187.9. I
